Ravens' Breshad Perriman: Misses practice with knee injury

While there hasn't been any suggestion of a major injury, Perriman does have a worrisome history of knee issues. He's yet to have any luck in his role as Baltimore's No. 3 receiver, catching just four passes for 26 yards on 15 targets this season. It will be tough for the team to justify keeping Perriman in that role if his efficiency doesn't improve soon.
